Festo
551668
Standard cylinder DSNUP-16-25-P-A
The Festo 551668 is a double-acting industrial component featuring a 16 mm piston diameter, a 25 mm stroke, and an M6 piston rod thread conforming to the ISO 6432 standard. Designed with flexible cushioning rings at both ends, a piston, a piston rod, and a cylinder barrel, it operates on compressed air within a 1 to 8 bar working pressure and a -10 to 60 °C ambient temperature range. This unit provides a theoretical force of 121 N on the advance stroke and 104 N on the return stroke at 6 bar, while including position detection for proximity sensors and a CRC 2 moderate corrosion resistance classification.
